1. Product Introduction
This steel structure primer is a two-component polyurethane coating specifically developed for use on steel structures and other metal materials. It is used to enhance the
adhesion between polyurea and the metal substrate.
2. Product Features
Low viscosity, low dosage, and quick application.
When used in conjunction with polyurea materials, it effectively enhances the adhesion between polyurea and the substrate.
3. Technical parameters
4. Scope of Application
This product is used as a companion material for spray polyurea coatings and is primarily intended for use on steel surfaces. If application on other substrates is desired,
please consult Huapo's technical engineers.
5. Packaging Specifications

6. Storage and Transportation
Store the paint in a sealed container in a dry, cool, and well-ventilated area, away from sunlight and rain, and away from sources of ignition.
Under the original packaging and specified storage conditions, this product has a shelf life of 12 months from the date of production.
Use promptly after opening. Reseal and store when not in use.
Avoid violent impact during transportation. Materials should be stacked neatly and stably.
7. Application Conditions
Surface Requirements: The metal surface must be derusted and cleaned. It must be free of dust, other debris, and moisture. If conditions permit, use HP-180 thinner to
clean the metal surface.
After surface preparation, proceed to the next step as soon as possible.
Ambient Temperature and Humidity Requirements: The application temperature should be between 5°C and 35°C, with the substrate temperature at least 5°C above the
dew point. The humidity range should be between 30% and 80%.
Ventilation: Maintain ventilation during application, but avoid strong winds.
8. Coating Methods and Requirements
8.1 Mix components A and B separately before use.
8.2 HP-112A:HP-112B = 3:1 (weight ratio). Accurately weigh the ingredients according to the ratio. After mixing, stir manually or mechanically for 3-5 minutes until
thoroughly mixed before use.
8.3 The mixed material should be used within 60 minutes. An appropriate amount of thinner may be added depending on site conditions. The material can be applied
by roller or brush.
8.4 Generally, the next step can be carried out 12 hours after application. If the interval between applications exceeds 48 hours, a new coat of primer is required before
application. If the paint is exposed to inclement weather such as rain after application, a re-application of the primer is necessary.
9. Recommended Dosage
Under normal circumstances, the recommended usage of this product is 0.1-0.15 kg/m².
10. Labor Protection and Safety
Before use, carefully read the product instructions and warning labels on the packaging and container, and familiarize yourself with the application method.
Open flames, welding, smoking, and any other unspecified activities are prohibited at the construction site. Application must be carried out in well-ventilated conditions.
The paint contains organic solvents. Wear a respirator and other protective equipment during application. Do not inhale paint mist and avoid skin contact with the paint.
If paint splashes on skin, immediately rinse with an appropriate detergent, soap, and plenty of water. If it splashes into the eyes, rinse thoroughly with water and seek
